It's easy to get up and running, has an intuitive object model and a handy Scaffold component for getting a data admin interface put together quickly. It stands up well compared to other .NET DALs I have used in the past e.g. NEO which I http://www.sourcemotion.com/blog/2008/09/comparing-linq-with-subsonic.htmlnoreply@blogger.com (Steve Sage)0tag:blogger.com,1999:blog-3147727977521057738.post-3204055661420003435Mon, 23 Jun 2008 08:25:00 +00002008-06-23T02:00:09.826-07:00Image replacementXHTMLCSSWeb designers like to use images for text because they can use non-standard fonts and have them nicely anti-aliased. There are a number of techniques out there that allow you to make this kind of image text accessible and search-engine friendly.One technique I have seen used is a negative text-indent (see http://phark.typepad.com/phark/2003/08/accessible_imag.html).For example, if you wanted to http://www.sourcemotion.com/blog/2008/06/css-image-replacement-techniques.htmlnoreply@blogger.com (Steve Sage)0tag:blogger.com,1999:blog-3147727977521057738.post-3160712390972152979Wed, 18 Jun 2008 16:52:00 +00002008-06-23T01:00:05.672-07:00XHTMLFCKEditorAs a postscript to my previous post about customizing the Subsonic Scaffold I also had cause whilst building an admin interface to pull out the XHTML value from the editor in a Javascript function.

The basic syntax is as follows: <cc1:Scaffold ID="Scaffold1" runat="server" TableName="Products"></cc1:Scaffold> Where SubsonicProvider is the name of the SubSonicService http://www.sourcemotion.com/blog/2008/06/customizing-subsonic-scaffold-control.htmlnoreply@blogger.com (Steve Sage)0tag:blogger.com,1999:blog-3147727977521057738.post-1364659194107785027Fri, 21 Mar 2008 16:26:00 +00002008-04-23T08:11:28.726-07:00validation controlsCheckBoxListASP.NETIf you try to use the standard ASP.NET validation controls to validate a CheckBoxList control you may receive an error message that looks like this: Control 'CheckBoxList1' referenced by the ControlToValidate property of 'RequiredFieldValidator1' cannot be validated Unfortunately out of the box the RequiredFieldValidator will not work on the CheckBoxList control.

Some are nice to have, some I now find completely indispensable. The SysInternals website (acquired by Microsoft in 2006) provides a number of tools which can be very useful to help developers diagnose system problems. http://technet.microsoft.com/en-us/sysinternals/default.aspxHere is a brief summary of some of the http://www.sourcemotion.com/blog/2007/12/toolset-part-1-sysinternals.htmlnoreply@blogger.com (Steve Sage)0tag:blogger.com,1999:blog-3147727977521057738.post-3708092029101664558Sun, 25 Nov 2007 19:20:00 +00002008-01-14T08:39:04.673-08:00Serialization.NETDeserializationXMLC#In a number of recent projects we have had to expose web services to third parties.
